my idea is from apple, because Macintosh is very famous with their logo. so i put an simple apple to maked your client knows that your company is specially and expert in Macintosh IT services
#55 This is much better. Can I see some variations. 1) A "bite" taken out of the right side of the logo 2) The Letters "IT" inside of logo in place of the "I" 3) Change the font. Current one is too hard to read.
